HVAC, plant and machine noise control in Diu
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space. Dense industrial estates with compressors, presses and generator sets close to offices, canteens and housing.
- At source
- Enclosure, barrier or anti vibration mounts at the machine.
- In the path
- Duct lining, attenuators and lagging on the first run out of the plant.
- At the receiver
- Only after the first two, and only for what is left.

01 / What it is
The material, and what it actually does on a Diu job
Noise with a source. Almost every honest fix is at the machine, the duct or the plant room, and almost nothing useful happens by lining the far wall of the occupied space.
Dense industrial estates with compressors, presses and generator sets close to offices, canteens and housing.
Work reaching us from Diu is mostly hotels and guest houses, restaurants and bars, heritage properties, offices, clinics.
- Salt air is relentless PET felt does not absorb moisture, rot or corrode. On an exposed coast that is the whole material selection argument.
- Season dates are fixed Work has to finish before the season opens. Real dispatch and transit dates matter more than a marginally better price.
- Heritage stone buildings Thick masonry with hard finishes that hold sound for a long time, and a structure that usually cannot be altered.
- At source Enclosure, barrier or anti vibration mounts at the machine.
Full specification
Thickness, density, NRC by frequency, fire class, standard sizes and build-up detail for HVAC and plant noise control are on the main product page. This page covers what that means for a project in Diu.
02 / The build-up
How the layers stack, from the structure inwards
-
Layer 1
SoundBlanket mass loaded vinyl
A limp, high density sheet that adds mass to a partition, floor or duct without adding depth. In Diu, dense industrial estates with compressors, presses and generator sets close to offices, canteens and housing.
Wall, decoupled. Independent stud, membrane between the boards, cavity absorption, two boards. The membrane is one part of a system, never the whole answer.
-
Layer 2
Soundproofing materials
The blocking side of the range taken together: mass loaded vinyl, resilient layers, cavity absorption and the build-ups they belong in. In Diu, auditoriums, banquet halls and places of worship are large hard volumes in concrete and stone where speech falls apart long before anyone calls the room echoey.
Independent leaf. A second wall that does not touch the first. Nothing else comes close for the money.
-
Layer 3
Wood wool acoustic panels
Wood fibre bound into a rigid board with an open texture. In Diu, classrooms are concrete and tile with bare walls and high ceilings, and class sizes push levels up. Corridors act as reverberation chambers that feed every room off them.
Direct fix. Mechanically fixed to the soffit or wall. Durable and simple.
Architects working in Diu usually need the build-up before the product. We will draw the section and mark what does the work. See how we support architects.
03 / Local conditions
The Diu conditions that change the answer
- Salt air is relentless
PET felt does not absorb moisture, rot or corrode. On an exposed coast that is the whole material selection argument.
- Season dates are fixed
Work has to finish before the season opens. Real dispatch and transit dates matter more than a marginally better price.
- Heritage stone buildings
Thick masonry with hard finishes that hold sound for a long time, and a structure that usually cannot be altered.
- Sensible quantities
A small market does not need a full container. We would rather quote a part load that works.
- Plant and HVAC
Dense industrial estates with compressors, presses and generator sets close to offices, canteens and housing.
04 / Room by room
What each space in a Diu project needs
-
At source
Enclosure, barrier or anti vibration mounts at the machine. PET felt does not absorb moisture, rot or corrode. On an exposed coast that is the whole material selection argument.
- SoundBlanket mass loaded vinyl, 2100 kg per cubic metre
- Acoustic foam and BassBloc, 20 mm
- Ceiling baffles and clouds, Made to the drawing, standard and custom
-
In the path
Duct lining, attenuators and lagging on the first run out of the plant. Work has to finish before the season opens. Real dispatch and transit dates matter more than a marginally better price.
- SoundBlanket mass loaded vinyl, STC 30, 5.25 kg per sq m
- Acoustic foam and BassBloc, 100 kg per cubic metre
- Ceiling baffles and clouds, Both faces work, which is why suspended area outperforms the same area laid flat
-
At the receiver
Only after the first two, and only for what is left. Thick masonry with hard finishes that hold sound for a long time, and a structure that usually cannot be altered.
- SoundBlanket mass loaded vinyl, STC 34, 8.4 kg per sq m
- Acoustic foam and BassBloc, 100 to 500 Hz
- Ceiling baffles and clouds, ASTM C423
Interior designers tend to arrive with the look already decided. We will tell you which finish gets there without losing the acoustics. See how we work with interior designers.
04 / Climate and durability
Durability in Diu, before acoustics is discussed
Diu is hot summers, mild winters and a distinct wet season, and that narrows the material list before acoustics is discussed.
PET felt handles the wet months without absorbing moisture or feeding mould. Timber and wood wool want a ventilated cavity and a stable indoor RH.
The failure we design against here is wet-season humidity behind linings.
On a Diu job with a consultant involved, our part is material that matches the submitted data. See working with acoustic consultants.
06 / Worth knowing
The six errors that cost the most
-
Absorption on the office wall for a plant room problem
Plant noise treated as a room problem is the most reliable way to spend a budget and change nothing anyone can hear.
-
Lagging a duct that is carrying the noise as breakout from the fan
Enclose the machine, break the vibration path, then deal with what is left. Doing it in the other order costs more and achieves less.
-
Ignoring structure borne vibration through the mounts
It sounds like a small detail until the room is finished and the complaint arrives.
-
Treating it as a generic Diu job
PET felt does not absorb moisture, rot or corrode. On an exposed coast that is the whole material selection argument.
05 / Getting it there
Supply into Diu, start to site
| Made at | Our own plant, Palwal, Haryana |
|---|---|
| Reaches site in | three days |
| Dispatch | 2 to 4 working days |
| To site | three days |
| Support | Drawings, build-ups, BOQ and material that arrives complete |
Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
By road from Palwal, roughly twelve hundred and fifty kilometres, normally three days on a dedicated truck.
Questions from Diu projects
What makes HVAC, plant and machine noise control different in Diu?
Dense industrial estates with compressors, presses and generator sets close to offices, canteens and housing. PET felt does not absorb moisture, rot or corrode. On an exposed coast that is the whole material selection argument.
Where should the budget go first on a Diu project?
At source. Enclosure, barrier or anti vibration mounts at the machine. In the path. Duct lining, attenuators and lagging on the first run out of the plant.
Do you have an office or installation team in Diu?
No. We manufacture in India and supply into Diu. We give you drawings, build-ups, a BOQ and material that arrives complete, and we will tell you plainly when a job needs a local contractor we cannot be.
How does material get to a Diu site?
made at: Our own plant, Palwal, Haryana, reaches site in: three days, dispatch: 2 to 4 working days. Standard items dispatch in 2 to 4 working days from our plant at Palwal. Grooved panels and custom colours take longer, and we say so before you order, not after.
What goes wrong most often on this kind of project?
Absorption on the office wall for a plant room problem. Lagging a duct that is carrying the noise as breakout from the fan.
What do you need from us to quote?
A plan, a section through the critical partition or ceiling, and what the room is for. From that we can give a build-up and a BOQ rather than a price per square foot.
